steps:
I created a bootable usb, config the bios to boot from the usb drive.
press "try ubuntu before you install it" ubuntu 12.10 and 12.04 on my new desktop,
it is failed.

what i tried after failed:
1. I have tested the usb drive image without any error.
2. There are guys suggested to disable secure boot for UEFI bios, tried but failed.
3. I tried pressing F2 to see the log, it shown as below
generating localed....
DONE
and the process is hanged.

Can anyone give me some advice?

What options are there when booting Ubuntu from a USB or CD?

You have two options when booting from a bootable USB or using a LiveCD.

The first option is:

Try Ubuntu

The Try Ubuntu option allows you to try Ubuntu without permanently installing it and altering your system. It creates a environment, run by the files on your CD/USB and using the hardware on your computer. While in this state, your hard-disk is not affected and no changes are permanently made to your system.

The second option is:

Install Ubuntu

The Install Ubuntu option permanently (unless you want to remove it) installs Ubuntu onto your computer, and from that point on will use your hard-drive to save files and to operate off. If you choose to dual-boot with Windows or OS X, you are able to choose which one to start at the boot of your computer.

Good luck!

i already tested "Try Ubuntu" option but failed by a bootable usb. Is there any other options ? thanks

Do you want to install Ubuntu, or just try it?

This has nothing to do with what the user is complaining about. pretty sure he knows how to boot either to try or install, but something is going wrong.
